Private Blockchain Evaluation Kit
====================
We expect this evaluation release to be useful for the following purposes:
1. Application developers who plan to eventually deploy their application to public Nxt blockchain.
2. Businesses evaluating the suitability of the Nxt platform for their own private blockchain use case.
3. Academic research and experimentation with proof of stake blockchain technology.
4. Users who want to learn how the Nxt blockchain works, without having to purchase NXT or ask for testnet coins.
Using the "Private Blockchain Evaluation Kit" solution, users will now be able to rapidly prototype, develop and test Nxt-based applications on a private, local testnet, without having to join the public testnet or the production blockchain.
—----------------------------------
This is an evaluation version for testing only. Source code is not provided.
This Private Blockchain Evaluation Kit is a testing and evaluation version
based on NRS release 1.11.4.
It contains the following modifications:
There are 10 hardcoded genesis recipient accounts with passwords "0" to "9"
and 100,000,000 NXT initial balance each.
The genesis account with a password of "Nxt" is allowed to send transactions
even though its balance is negative.
The software is configured to run as testnet only, ignoring the value of the
nxt.isTestnet property.
The peer networking port has been hardcoded to 5874.
All modifications specific to the current Nxt public blockchain have been
removed.

This letter was originally published as part of the Nxt Foundation Marketing Strategy 2017 document and was intended to be read together with it and the accompanying announcement on Nxtforum.org.
A lot of things have changed since the launch of Nxt in late 2013. One of those that stood out to me when I came back in mid-2016 after a 2-year hiatus was how less decentralized things were becoming, which has its pros and cons. I remember sending a tweet to what is now considered as the official Twitter account back in the early days and being told that there’s no such thing as an official account since Nxt was a decentralized platform. Just as BCNext thought, things can’t be completely decentralized, though whether Nxt found the level after which a society can’t function as a whole or not is arguable. In any case, some centralization has occurred, both with the Foundation or with Jelurida, the corporation created by the core development team. The creation of both has led to some mixed reactions. For some, it was enough to leave Nxt or solidify their interest in the platform. However, Nxt is still largely decentralized. The Nxt and, soon, Ardor blockchains can be used without permission from either of the two and will never need it. Network consensus is also untouched, which is another reason why the ARDR distribution was 1:1. On the extreme end, even if the Foundation and Jelurida were to disappear instantaneously, the code would still be available and the current version would still be running. Remaining users could create a Foundation of their own as well. It probably won’t be easy to do, but it would be possible.

As a lot of those in the community know, Nxt didn’t have the same start that other platforms have, with only 21 BTC raised in 2013, all of which were long gone by the time the Nxt Foundation or Jelurida came into existence. Also, a number of early projects were either voluntary or funded through bounties by the early members of the community. Aside from core development tasks, everything else was organized in a decentralized manner, whether it was creating tools for community members or creating committees to fill various necessary roles. This is still being done today, though to a lesser degree, due to the various initiatives and 3rd party projects on Nxt and those planned for Ardor. Even a large factor of the Foundation being able to fulfill its role within its first official year even came in the form of donations from community members through the Tennessee Fundraising project with nothing but work promised in return. In a lot of ways, the beginnings of Nxt, coupled with an anonymous and now non-existent founder, matches that with Bitcoin’s. While further funding options are being explored by both parties, whether they be internally or externally, it is clear that the reason why Nxt has lasted so long is because of the cooperation of the wider community behind it, not just the Foundation and not just the core developers. It will also continue to be the key for Nxt and Ardor to go into the future.

While BCNext’s Plan focused mostly on the decentralization aspects of network consensus, I think that this following quote can apply at a community-level as well.
Without cooperation, Nxt becomes weak and can be easily attacked. It's like a system in unstable equilibrium. If people stop caring about cooperation, Nxt will fail very quickly.
Thank you for reading my letter and thank you for being part of the community. If you have any questions or comments, good or bad, please feel free to contact me directly through Slack, Nxtforum, Reddit, or email. I look forward to working with you as Nxt and Ardor move forward.

As an NXT developer I get to talk with many people and businesses about their plans of using blockchain.
One issue that comes up every time is scalability. It is now clear for everyone in the industry that traditional blockchain architectures like Bitcoin, Ethereum and NXT 1.0 does not scale.

We are working on an Ardor child chain pegged to BTC where the peg is ensured by a 3rd party business such as crypto exchange. You'll be able to convert "real" BTC to child chain BTC at 1:1 ratio and then exchange these BTC using the on blockchain coin exchange to Ardor or Ignis or you'll be able to trade existing assets directly against these child chain BTC so that asset price is denominated in BTC.
Similarly we are planning an EUR pegged chain and perhaps also a USD one.

Introduction to Smart Phasing

As explained in the nxt wiki https://nxtwiki.org/wiki/Phasing , Phasing is about deferring the execution of a transaction until certain conditions are met.
Currently, phasing approval models and minimum balance models allows flexible definition of approval rules for a transaction (a.k.a “Smart Transactions”), however, they cannot be mixed and matched to provide more functional approval modals.
Smart Phasing
To support more advanced phasing logic, we now added to Ardor the ability to create "Composite" voting models.
A composite model defines the voting models building blocks and the logic to bind them into an "Approve" or "Reject" decision.
The composite model supports the AND (&), OR (|) and NOT (!) logical operators and defines an expression which applies these operators on a combination of simple voting models.
Examples:
Using a NOT operator, allows you to setup a "dead man switch" so that funds are transferred to another account only in case an account did not approve this transaction until a certain height i.e. the account owner is assumed dead.
Using a NOT and AND operators, you can define that a transaction is approved at certain height only if none of the accounts in the whitelist has voted against it.
You can also define more complex conditions like approve a transaction only in case an account from a whitelist (i.e. a regulator, manager, judge etc) has approved it OR an account holding a certain number of tokens approved it i.e a user a stake holder etc.
